why does qb not let me save Journal Entry when entering accounts payable and listing a vendor in the name

Hey there, @accounting633. I'm here to resolve your issue with saving the Journal Entry (JE).

Before anything else, I'd like to know if you get an error message when you try to save your JE.

In the meantime, we can perform some basic troubleshooting steps to fix this. Let's start by signing in to your account via incognito or private mode to avoid storing cache data files that can cause errors when using a web-based program.

Here are shortcut keys you can press in your typing board:

• Google Chrome: press Ctrl + Shift + N
• Microsoft Edge: press Ctrl + Shift + N
• Safari: press Command + Shift +N

Then, recreate the JE and save it. Once this works, clear the cache of your default browser to remove accumulated data. If the issue persists, you can use another supported browser or device.

For future reference, if you want to allocate a transaction between two accounting periods or fix a debit and credit error, refer to this informative article: Reverse or delete a journal entry.
